GUN.

I Application filed June 9,

citizen of. the United States, residing at Birmingham, in the county of Jefferson and State of Alabama, have invented certain new and useful Improvements in Guns; and I do hereby declare the following to be a full, clear, and exact description of the inven tion, such as will enable others skilled in the art to which it appertains to make and use the same. f

This invention relates to improvements in guns, and more particularly to such as are provided with a plurality of barrels or cylinders through which charges are to be fired, such as a double barrel shot gun, and the object in view is the improvement of the triggermechanism for enabling the control, selectively and consecutively, of the firing means by the employment of a single trigger.

A more detailed object is the safeguarding against unintentional or accidental firing of the second barrel incident to involuntary second pulling of the trigger after first firing.

\Vith these and further objects in view as will in part hereinafter become apparent and in part be stated, the invention comprises certain novel constructions, combinations and arrangements of parts as subsequently specified and claimed.

In the accompanying drawings, Figure 1 is a view partly in side elevatio and partly in vertical section of a gun incorporating an embodiment of the features 'of the present invention, a part of the stock being broken away and omitted for facilitating clearness of disclosure, and a fragment of the barrel being broken away for the saving of space, the'parts being seen on the scale of the actual size of an ordinary commercial gun, the parts being shown in full lines in the position immediately after cock- "Figure 2 is a'similar view of the same looking from the opposite side.

Figure 3 is a horizontal section taken approximately on the planes indicated by line 3-3 of Figure 1, and looking downward, the parts being shown on a magnified scale and in the position seen in Figure 1, the selective mechanism being set for first firing therighthand barrel. a

parts being seen in elevation and parts omitted for clearness, the parts being in the position ust before firing Figure dis a similar view of the same with the parts in the position while or immediately following firing of the righthand barrel and before the trigger is released.

Figure 6 is a similar view of the same with the parts in the position after such firing and after the trigger is returned to position for enabling firing of the other barrel.

Figure 7 is a fragmentary, vertical section taken approximately on the plane indicated by line 77 of Figure 3, partsbeing omitted for clearness of disclosure, and the parts being shown in the position seen in Figure 3.

Figure 8 is a detail elevation of the trip block detached. I

Figure 9 is a transverse section taken on the plane indicated by line 99 of Figure 4. ,Figure lO is a transverse, vertical section taken approximately on the plane indicated by line 1010 of Figure 1, and looking in the direction indicated by the arrow.

Figures 11 and 12 are detail views of the trigger and selective slide detached.

Specifically as illustrated, the embodiment of the invention shown is applied to an ordinary double barrel shot gun to which it is especially well adapted, it being one-0f the objects of the invention to enable the application thereof to such a double barrel shot gun as is already in use by the substitution of a selective firingslide for one .of the triggers, and the substitution andaddition of certain other parts as hereinafter described in detail. For the sake of brevity and avoidance of unnecessary discussion and unnecessary drawing, the details of the firing mechanism of the shot gun are omit ted, such details'being well knownto those skilledin the art, the same firing mechanism being employed and being controlled by the same sears modified only in their rear end construction for adaptation for use in connection with the other parts of the shown embodiment of the invention.

WVith this understanding, referring to the drawings by numerals, .1 indicates the stock of a double barrel shot gun containing the ordinary firing mechanism controlled by the present improved trigger mechanism, and

rels 2 having the usual breech lock release t 7 which is bifurcated and a safety locking 3 and safety actuator plunger 4,:all. of which are well known parts and operate in the usual manner. A bracket 5 upstands Within the stock, being preferably fixed at its lower end to the trigger plate 6 of the stocksocket,

and at its upper end having'an oifset arm portion so as to be of a widthsuflicient to effectively cooperate with the parts with which it engages, ashereina'ft'er described. The laterallyenlarged portion is provided with a downwardly-extending ofiset web or projection 12' at its rear portion, which pro jection12 has a downwardly-extending fin gen '13 at one side. 'Theashoulder or end portion of the lever in front of the Web" 12 is provided with a depending-point or lug 14 having a forwardly beveledend adapted to cooperate with the parts hereinafter mentioned.

"Upstanding from the trigger plate 6 is a flat bracket 15 arranged with its faces longitudinally of the gun and commonly employed with the ordinary double bar-rel shot gun for carrying the trigger pivot and guiding the triggers arranged at opposite sides of the bracket. In the present improved construction, a; pin 16 extends'throug h the braeket 15 andpivot'ally retains the trigger web 17 in place; The web 17 extends through a. slot-18in the plate 6 in the usual 'nranner and is provided with the usual triggem-19. Thepart 17 iS, -l{1 fact, a relatively thin web extending vertically and longitudinally through and above the slot 18, and the upper-edge of said web is cut away to form adepression on notch 20 undercut at-its ends to fo-nn' a forwardly-extending, open-ended slot 21, and a iearwardlvextending, openended-slot 22, the material a of the trigger Web'li' upstanding above the slot 22- and:be-'

' ing for-med withan ofl'set orashould'er 23 pro ducing an enlargement atthe openend of the slot 22. The shoulder 23 is inclined vfrom its lower edge 'nearwardly/ and the overhanging portion of the material of trigger web '17 above the .slot22wforms a. hooklike port-ion 24.1 A .pin 25 is fixedf to "the *lower portion i of A the reaniterminus. 0f the trigger web 17 .andextends laterally to the right thereof forserving as a idetent'ia-nd actuatoi for the selective slide 26. v Theslide consists of a sheet or web extending through the slot 27 and'lying parallel to the the two barrels;- 1

longitudinal slot 28 through, which the re-- spective outstanding end portion oft-he in 16 extends- $hde26 extends reanwa-r ly from'the'pin and is formed with cut-away portions, leaving an upstanding projection 29 located to cooperate with one or the other of the. scars hereinafter described, accord-1 ing to whether the slide 26 is located at the front or rear extremityof its lon 'tudinal movement accommodated b the 28' in engagement with pin 16. he slide 26 extends rearwardly beyond the upstanding project-ion 29=and has a dependingprojection or lug 30 adapted to-engage one-side or the other of the laterally-extending in 2 l When the pin 25 engages, the rear ace oflug 30, the portion 31 ofthe lower edge of slide 26 rests upon'the pin and is adapted to be lifted by the pinfwhen the trigger is moved or pulled: for efiectinga firing-ac- =t1on, and, when the slide 26is mo'ved rearwardly until the pin 25 engages-the front 7 face of the projection 30, "the portion 320i the lower edge ofslide 26 rests upon the pin 25, so-that-the slideisadapted; to be lifted by the movement incident tothe-pulling of the trigger. The parts are proportioned suchthat when the pin25 engages theportion 32 of the lower edge of slide 26, the

projection 29 will lie beneathcand in position to operatively engage a. "portion of one of the scars, and when the pin 25'engages the portion 32, theprojection 29 will lie beneath a, portion of and in position to operate'the othersear when the slide 26 is-elevated by the lifting action of the pin 25 incidenttoa pull upon the trigger; The'Web comprising I the slide 26 is proportioned to loosely-occupy and extend throughthe slot in the trigger plate 6, conresponding to the ordinary'trig- .ger slot, and the plate or slide 26 is provided with a preferably lmu'rled or otherwise suitably finished operating grip 0r handle lying outside ofand beneath-the,trigger plate 6, so that the operatormay freely slide 7 j the plate-26 to eitherof its positions for bringing projection 29 intooperative :rela tron with either of the sears. Thus. selective V engagement of the sea-rs :by the plate; 26 is provid d for. Itbeing apart of; thepresent invention to provide :th tthe sear to "be actuatedis the one engaged by the p-rojec-- tion 29, it; is only necessary that revision be made that the other sear sha l not actuated at the time, of'first actuationof a:

on the second actuation o-r pullingof the .tnggQE- bothsears shall be actuated to insu bot suc e i and; l i firin e sear by the projection 29, and that thereafter To this end, the "seat -eased areprpvided with rear constructions ofspeeial"; 10-,

3, the sears being otherwise, that is, in their forward portions, identical with the ordinary sears of a double barrel shot gun. The forward portions of the sears have, therefore, not been shown, and it is understood that the firing mechanism or lock'is or maybe of any'of the well known types influenced or actuated to operate under the actuation of said sears. Each of the scars 35, 36, is provided at its rear endwith a lateral arm 37, '38, which arms lap each other immediately above the slide 26 and in position to have the projection 29 located beneath the arm 38 of sear 36 when the slide 26 is in its rear position, that is, when the pin 25 engages the portion 32, the arm 37 beinglocated to overhang the projection 29 and be engagedthereby when the slide 26" is in its forward position, that is, when the pin 25 engages the portion 31. At the place of overlap of the arms 37 and 38, the saidarms are-preferably notched, as clearly seen in Figure 3, so that the cut-away portion or notch of one accommodates the projecting portion of the other, and, therefore, thetwo arms 37 and 38 may be and are arranged in alinement transversely of the stock so as to be readily engaged and easily underhiungby a part adapted to actuate both of the arms 37 and 38 at one time.

To effect such actuation, subsequent to the action of the projection 29 on one of the sears, a' sliding trip block 39 is mounted on the triggerweb 17 at the place of the notch 20. The sliding block 39 is provided with a longitudinal, open-edged slot 40 foraccommodating the upper portion of the trigger web 17 therein, the side portions of the block 39 lying parallel to and at the sides of the trigger web 17, or in other words, astride of said trigger web. A guiding and pivotpin 41 extends through the forward portion of the block 39 and through the slot 21 so as to'enable longitudinal shifting of the block 39, and at the same time enable pivotal movement thereof. The block 39 is notched or cut-away at 42, leaving a forward, upstanding portion and a transversely-disposed, upstanding loop 43 near the rear portion. A shoulder 44 extends rearwardly and upwardly within the notch 42 at the opposite sides of the slot 40 in position for at times unclerhanging the arms 37 and 38 of-the sears for purposes hereinafter set forth. A rod 45 is set in a socket in the rear edge portion ofthe bracket 15, and is arranged on an incline extending rearwardly and upwardly into a recess in the block 39, atone side of the slot, and slightly below the pivot 41, as best seen in Figure 8. A coiled spring 46 surrounds the rod 45 and is tensioned to stress the block 39 in a manner for'pressing the block both rearwardly and in a direction for causing the rear end to tilt upward or swing upward on the pivot 41 when free to do so. A preferably transversely-square pin 47 extends through the rear portion of the block 39 below and in line with the front portion of the loop 43, the said pin extending across the slot 40' and being provided with an inclined upper surface adapted to cooperate with the shoulder 23, as hereinafter stated. It will be apparent to those skilled in the art that while the part 47 by preference, because of convenience of construction, is usually made in the form of a pin and assembled by a riveting action, the block 39 could be otherwise formed to provide the portion of the pin lying across the slot, and so long as properly shaped and located the part would function whether made in the'form of a pin or made integral with the block or otherwise. Extending rearward of and below the loop 43, the block 39 is formed with projections 48, one at each side of the slot 40. The block 39 is proportioned to have that part of pin 47. extendingacross slot 40 lie at all times in the slot 22, either in the lower portion or in the upper portion thereof, the pin 47 being spaced from the pin 41 a distance suflicient for preventing the possibility of longitudinal movement of block 39 suffi cient to enable escape of the-blockfrom the trigger web 17. As the spring 46 stresses the block 39 rearward, and at the same time tends to lift the rear end upward, the pin '47 will engage the shoulder 23 and liein the upper portion of slot 22 whenever free to do so. The shoulder 44 is also so located that, when the pin47 contacts with the shoulder 23, the said shoulder 44 will lie in a position forward of the arms 37 and 38 ofthe sears, but, when through anymanipulation, the pin 47'is forced to enter the lower portion of slot 22 and caused, by the action of spring 46, to travel to the rear end-of said slot 22, so that the hook 24 extends throu h the loop 43, the shoulder 44 will thereby e caused to lie beneath portions of the arms 37 and 38. Thus, when the pin 47 engages the shoulder 23, the block 39 may be elevated without influencing either of the scars, but, when the pin 47 hasbeen causedto move rearwardly in the lower portion of slot 22, the shoulder 44 will engage thearms 37 and 38, and then, if the block 39' is elevated, both sears will be elevated to an operating position. y f r The safety-lock lever 8 is arranged to have its upper portion in line with the rear end of plunger 4, so that, whenever the release lever 3 is swung laterally for releasing the breech lock, the rearward thrust of the plunger 4 incident thereto will cause the plunger to strike the lever 8 above the pivot and shift the same to the safety position indicated in full lines in Figure 1.

In operation, thegun is cooked "in the usual manner by the opening and closing of the breech-incident to which the lever 3 must be manipulated, and, as a result of which, the parts are brought'to the position indieated infull lines in Figure 1. As is well knowmthe rear portions of the sears 35 and and 36, are practically in the same positions after-the gun is ;cockedas before, but are so adjusted; that an upward movement "of the rear end of eitherof the sears will fire vthe particular barrel controlled by v that sear. The-partsnbeing in the'position stated and the gun being cocked, ;the shoulder 44 of block 39 will-bein front and slightly spaced 7 1 end of the web 17 while-the rear end of block froni the plane of the foremostportions of the arms 37 and38, and the selective slide v 26 will be positioned withthe projection 29 ordinary gun for firing.

located beneath-the arm 37 the-portion 31 of the slide26 resting onthe pin 25. The leverS-islocated with its projection 12 inn-- niediately. above the trigger, thegreduced portion resting against thevv upperedge -of the hook 24 while the extension l3iextends past the upper edge of hook 24 and engages one-of the. arms 48 of the sliding trip block 39. The parts are thus effectively held againstfiring or other operation than the possible shifting or theslide 26, 'as,hereinafter stated Now, if the operator wishes vto fire the; righthand barrel, he merely'pushes' theslide 4;up. f0rwardly along the stock socketinthe; usual manner of releasing an It is only necessarythen for him to pull on the trigger 19 to fire the righiha-nd barrel. The pull on the trigger 19, causing the trigger web 17 to swing upon its pivot 16,-causes the pin 25 to lift the rear end of the slide 26, swinging the slide on its pivot 16 and thereby lifting the projection 29 sufiiciently for rais-. ingthe arm 37 and elevating the sear. to the hammer-releasing position. When the slide 4 is moved forwardly to the position for'releasing the safety latch, the lever '8 moves to the position shown inFigures4 and 5, wit-hthe' projection 14 located im: mediately above the loop 43 of block 39, so

that when the trigger 19 is pulled for eifect+ ring the firing asjust' described, the upward movement of the hook end 24 of web 17 carriesup withit the reariend of the block 39 until-,theloop {43 strikes the projection '14, the loop 43 remaining in a position upstand ing' above ;the hook 24 and ,being; actually elevated by the stress; of the spring 46 plus theaction of the pin 47 in having its inclined, faoeoverlap the inclined face :of shoulder 23. When the upperextremity of the loop. 43 strikes projection 14,,the loop is held against further upward movement {thereby- It .Will be apparent that until this contact, is e-ilected, the pin 47 wi-llremainin theenlarged-rear portion of slot'22 invengagement with the shoulder '23.; This engagement isassured by virtue of-ithe fact that the shoulder 23-is beveled orinclined,

and the rearedge of the pin 47, whiehem gages the shoulder 23, is correspondingly inclined to cooperate therewith and be held thereby against the possibility of dropping down. The pressure-of spring-47 stressing thecblock 39 rearwardly,a nd, atthe sum time tending tolift or'elevate the rear: end

ofthe block 39, also insures retentionof the pin 47 in engagement with the 81101114815223.

However, during the first firing, when the trigger is pulled and theloop 43 is ilhlBrQlQ- vv-ated-to contact-with the lugor projection 14, further upward movementvaof the rear 39 is held againstsuch movement by engagement of loop .43 against projection 14, causes the hook 24 to'vrise above the pin and brings the narrower, lower portion 0! slot 22 in linewith "the pin14t'.v The moment this position is reached, the spring 46 ads to move the block 39 rearwardly "a very slight distance represented by, the distance from the rear. face of the-shoulder 44 to the front face ofothe adjacent arms 37 and '38,

this spacebeing clearly seen in ;Figum. The shoulderi44 thus moves up into mum with the 31111837,: 3 8,and the parts assume the position shown 1n Figure 5 with the 011+ treine edge of pin 47 underlapping theex- 37, 38, will linsurea lifting of both of said u armswith theneX-t pull of the trigger 19, whereby the second or lefthand 7 barrel is fired uponthe second pulling of thetliigger. When the trigger has been pulled theseeond time, it hein-gunderstood, of course, that the searsalways return. after a firing operation to their forinerposition, the parts are in the positionshown inFigure 6, whiclsifiavidensticaljwhether after the first firing or after the second-firing; It is now desirable to Island and cock the gun, and this is done in the usual mannenby the. operation of the lever '3 followed by the breaking, loading and re storing of theparts i'tothe position seen in full lines in .FigureLfVVhenthe lever 3 is manipulated to release the breech lock, the plunger '4 isv given a rearward thrust, by mechanism not illustrated, but of the ordinary typec-oimnonly i-n-use, and m r-ward thrust causes the rear end g-of the plunger 4 to strike the upper lever 8, which effectsa swinging ofthe lower portion in a forward direction. parts starting from the position seen in Figure 6, the projection 19 engages the rear edge of the loop 43 and stresses the same forwardly against: the pressure of the spring 46. As the extension 12 and linger iii are slightly inc-lined forwardly and downwardly, they exert a slight upward lifting action on the loop 43, but whether this action occurred or not, they press the entire block 39 forward until the pin 47 is moved out of the lower or narrow portion of slot and into position for engaging the shoulder 23, and the spring 4:6 stresses block 39 to lift the rear end of the block so as to bring the extreme edge of pin 1-? to overlap the extreme edge of the shoulder 23, so that, when the slide 4 is moved forwardly for releasing the safety lock and the projection 12 is moved backward out of engagement with the loop 43, the block is free to move and does move slightly upward and rearward until the pin t? is fully seated against the shoulder 23. Thus, in the first part of the cocking operation, the trigger parts are restored to their former positions with the shoulder l4: forward of and out of line with the arms 97 and 38, and the parts are again in position for another firing ope-ration.

The gun being cocked and the parts being in the position seen in Figure 1, the operator releases the safety latch and then, desiring to tire the leftha-nd barrel instead of the right, presses the grip 23 rearward. lhis causes the slide 26 to move from a position with the portion 31 engaging pin to a position where portion 32 engages the pin and this brings the projection 29 from the position underlying the arm 37 to a position underlying the arm 38. Now, if the trigger is pulled, the le-fthand barrel will be fired by the action of the projection 29 against the arm 38. All of the other parts remain the same as above described and function as stated. It will be noted that the shoulder 44 is disposed out of vertical alinement with the arms 37 and 38 until the first tiring, and upon the completion of the trigger action incident to the first tiring, the block 39 assumes the position seen in Figure 6 with the shoulder 44 underlying the two arms 37 and 38. and upon the next pulling of the trigger the righthand barrel will be tired.

As is well known to those skilled in the art to which the present invention relates, it is the common experience of operators that. after tiring a gun, the trigger finger involuntarily, and in many instances unbonsciousl phmakes a second pull upon the trigger. 1.h a double-trigger gun or a pump gun, this spasmodic or involuntary pull is harmless, but. unless guarded against. it would in the present improved structure cause the second barrel to be tired when the operator did not wish it. The trip block 23$) and cooperating parts are, therefore, espe cially constructed to prevent such action. Upon the firing of the first barrel, and the consequent release of block 39, said block, owing to its inertia being overcome quick- 1 lags in its rearward movement, and such movement is interrupted by the detent pin 47 coming into engagement with the shoulder 23. The sudden recoil of the gun causes such rearward movement of the parts as to relieve the stress of the trigger linger on the trigger and part 19 momentarily, at the time of recoil, is allowed to return to its original position, but, as the trigger linger is still pulling, not having relaxed, the operator will without intent or even knowledge of the fact cause his trigger linger to catch up with the trigger, in its position assumed incident to the recoil. and give a second pull upon the part 19. This invariably occurs in the use of firearms, and is known as the recoil. pull. it happens so quickly that no marksman can prevent it. Hence, I have safeguarded against it by providing the de tent pin 47 and shoulder 23 which effectively and invariably intercept the movement of block 39, and thus heads off the second or recoil pull of the trigger. The function of block 39, therefore, affords absolute assurance against any likelihood of doubling or accidental firing of the second barrel.

It should be borne in mind that. since the operating parts above described are all concealed and probably not understood by the operator at all, the guide for the operator in the matter of firing one barrel or the other is the position of the grip or handle 33. If it is located in its forward position, then the righthand barrel will be tired first when the trigger is pulled, but if the handle or grip 33 is in its rearward position, the lefthand barrel will be first fired.

The accompanying drawings illustrate and were carefully copied from an actual operative structure, it having been found dcsirable to magnify the showing to disclose the details and enable an accurate reading of the drawings. It will be observed also that while every part in the mecluu'iism shown and described is made with great prccision and functions exactly as rcquirct'l, so as to be reliable and dependable at all times, there is with practically every moving part. a degree of looseness enabling read and easy n'iovement and the assurance of the adaptation of the part to its functions in its relation to all the other parts, and, while this looseness enables the required play for insuring case of operation of the parts, the proportions are such as to always assure cll'cctivcucss and provision of functioning. As, for example. the projection it has it free cud beveled otl' t'or .\'ardl v so that if, in any instan e, the slide --l should be pushed far enough forwardly, as when it. is being litl manually released, to allow the loop 43 to have its rear edge pass in frontof the projeetion 14, Since the said loop is free to swing upward, there will he muckin aetion between the loop and projection 14, heeaiie :iii'iovenio'nt of either of the parts will cause greaniining action between the loop Zllld the inclined or beveled frontof projection 1-1. This beveled front, however, does not interfere in the least with the functioning of projection 14 in retaining the loop eggxinst rising withthe hook 24 under the first aetuzttion'of the trigger after cocking What is olain'iecl is:- I 11.
